BAD::1 March 2006 (Factorial Usage)

1 March 2006 in MM/DD/YY format is 03/01/06.

The following demonstrates the factorial function.

   0! = 1
   1! = 1
   2! = 2 x 1 = 2
   3! = 3 x 2 x 1 = 6
   4! = 4 x 3 x 2 x 1 = 24
   5! = 5 x 4! = 5 x 24 = 120

1 March 2006 is a BAD if factorial is used.

   date: 03/01/06  
   numbers: 3, 1, 6

BADs are a form of equationeering and here are more BAD equations.

   3/1/06:  1 * 3! = 6
   3/1/06:  3!^1 = 6
   3/1/06:  (6 % 3)! = 1
   3/1/06:  (6 - 3!)! = 1
   3/1/06:  summation(1, 3) = 6
   3/1/06:  (1 + 3!) * 6 = 42                   [bad42Eval]
   3/1/06:  1 + 3! * 6 = 37                     [bad37Eval]
   3/1/06:  1 + 6 / 3 = 3                       [badCardinalityEval]
   3/1/06:  cuberoot(summation(1, 3!) + 6) = 3  [badCardinalityEval]
   3/1/06:  median(1, 3, 6) = 3                 [badCardinalityEval]
   3/1/06:  cuberoot(sqrt(3^6)) / 1 = 3         [badCardinalityEval]

bad42Eval: Find an expression that evaluates to 42.

bad37Eval: Find an expression that evaluates to 37.

badCardinalityEval: Find an expression that evaluates to 3 (i.e. the number of numbers in the date).
